الملخص EN

The strength characteristic is one of the important characteristics that play an important role in the level of achievement in most sports, including swimming, especially the activity of 50m freestyle swimming, as this activity depends greatly on the explosive strength and the characteristic strength of speed because of their effect on developing the muscles of the legs, and from the methods that are used in Strength development is a method of the polymeric training which includes types of jumping exercises.

Through the researchers' follow-up to the training process, they noticed the lack of giving swimmers the polymeric exercises, and the researchers believe that these exercises are important for their use for developing muscles and improving performance.

Therefore, the researchers decided to prepare a training curriculum in the style of the polymeric and to identify the effect of the approach in developing the explosive strength and the characteristic speed of the muscles of the lower limbs, as well as identifying its effect on the achievement of a 50m freestyle swimming.

The researchers hypothesized the existence of statistically significant differences between the pre-test and posttests of the research sample in developing explosive strength and strength characterized by speed, as well as the achievement of a 50m freestyle swimming.

The researchers used the experimental method of one group and the research sample was determined by the deliberate method from the swimmers of the national youth team, and the method was applied.

The training course, which lasted for (8) weeks, consisted of (3) training units in the method of the polymeric training.

After obtaining the raw results, they were statistically treated.

The researchers concluded that the proposed training curriculum led to the development of explosive strength characterized by speed and achievement.
